Bolt Graphics' latest offer, the Zeus 4c, outperforms Nvidia's RTX 5090 by a factor of 13 in path tracing tests, according to the company's carefully selected benchmarks, yet essential performance inquiries linger unanswered.
Next-Generation GPUs Take a Leap, but Bolt's Zeus GPU Platform Aims for a Quantum Leap
Bolt Graphics has unveiled its Zeus GPU platform, promising to outperform current and upcoming GeForce and Radeon cards in specialized real-world tasks like path tracing, CAD, and high-performance computing (HPC). The Zeus GPU is set to be released in 2027, with the high-end quad-chiplet 4c model claiming up to 13 times the ray-tracing performance of NVIDIA's GeForce RTX 5090 in simulated path-tracing workloads at 4K.
The Bolt Graphics Zeus GPU platform's unique selling point is its innovative features, including expandable memory up to 384 GB, built-in RISC-V CPUs, and ultra-fast connectivity. However, these performance numbers are based on pre-silicon internal simulations and developer kits, not third-party real-world benchmarks, so their accuracy is uncertain.
The Zeus GPU's focus on ray-tracing efficiency and specialized workloads means it trades off traditional rasterization shader performance. The shading performance of the Zeus 1c, for example, is 10 FP32 TFLOPS, while the GeForce RTX 5090 offers 105 FP32 TFLOPS in shading performance. This suggests that while the Zeus GPU may excel in professional rendering, CAD, and HPC applications, it may lag in gaming scenarios due to lower shader throughput and use of LPDDR5X memory with lower bandwidth than the GDDR7 memory in NVIDIA and AMD cards.
In terms of memory and hardware architecture, Zeus's expandable memory via DDR5 SO-DIMMs combined with fixed LPDDR5X modules is unique and allows very large memory capacities beneficial for large data sets in professional contexts. However, this setup may introduce latency and bottlenecks unsuitable for gaming. Power consumption is notably efficient, maxing at about 225 W, which is lower than or comparable to high-end GeForce and Radeon models, and Zeus uses standard 8-pin PCIe power connectors, simplifying integration.
In comparison, the upcoming GeForce and Radeon GPUs, expected to be released by 2027, are expected to focus on gaming and mixed workloads. While their ray-tracing performance is expected to be high, it is likely to be less than that of the Zeus GPU.
In summary, the Bolt Graphics Zeus GPU has the potential to significantly outperform 2027's GeForce and Radeon cards in real-world professional rendering and compute tasks involving ray tracing, if Bolt Graphics' claims hold true. However, for traditional gaming and general graphics workloads, the Zeus GPU is expected to lag due to lower shader performance and memory bandwidth limitations. Until third-party reviews and real silicon testing are available, assessment remains speculative but cautiously optimistic for specialized workloads.
